There must be a linear direction from less valuable to more valuable rewards as time or difficulty increase. I watch a youtuber as finished pillar on 59 and get a rare scroll as reward, not even an epic one. As of daily rewards, there must be a rare hero as reward after 25 logins on the first month, an epic on the second and a legendary on the third month to play the role of the carrot.
I really love the game, and I’m going to the second “restart” now at S3. After what season will I say, I can't go anymore through the same process from level 1 ???
